a4j:support within a rich:modalPanel
- by Andy Deighton
Hi all,
I've hit a wall.
I know the a4j and rich tags pretty well (I use Seam 2.2.0 and Richfaces 3.3.1). However, I'm trying to do something quite simple, but in a rich:modalPanel.
It seems that rich:modalPanels do not allow Ajax events to be fired. Here's a simple breakdown:
I have a h:selectOneMenu with some items in it and whose value is attached to a backing bean. Attached to that h:selectOneMenu is a a4j:support tag so that whenever the change event is fired, the backing bean should get updated. Truly simple stuff eh?
However, when this h:selectOneMenu is in a rich:modalPanel the onchange event doesn't update the backing bean until the rich:modalPanel closes.
I can confirm this because I'm running it in Eclipse debug mode and I have a breakpoint on the setter of the property that's hooked up to the h:selectOneMenu.
This is driving me mad! This is vanilla stuff for Ajax, but rich:modalPanels don't seem to allow it.
So, the question is: can I do Ajax stuff within a rich:modalPanel? I'm basically trying to use the rich:modalPanel as a form (I've tried a4j:form and h:form to no avail) that reacts to changes to the drop down (e.g. when the user changes the drop down, a certain part of the form should get reRendered). Am I trying to do something that's not possible?
Here's a simplified version of the modalPanel:
<rich:modalPanel id="quickAddPanel">
<div>
<a4j:form id="quickAddPaymentForm" ajaxSubmit="true">
<s:decorate id="paymentTypeDecorator">
<a4j:region>
<h:selectOneMenu
id="paymentType"
required="true"
value="#{backingBean.paymentType}"
tabindex="1">
<s:selectItems
label="#{type.description}"
noSelectionLabel="Please select..."
value="#{incomingPaymentTypes}"
var="type"/>
<s:convertEnum/>
<a4j:support
ajaxSingle="true"
event="onchange"
eventsQueue="paymentQueue"
immediate="true"
limitToList="true"
reRender="paymentTypeDecorator, paymentDetailsOutputPanel, quickAddPaymentForm"/>
</h:selectOneMenu>
</a4j:region>
</s:decorate>
</fieldset>
<fieldset class="standard-form">
<div class="form-title">Payment details</div>
<a4j:outputPanel id="paymentDetailsOutputPanel">
<h:outputText value="This should change whenever dropdown changes: #{backingBean.paymentType}"/>
</a4j:outputPanel>
</fieldset>
</a4j:form>
</div>
</rich:modalPanel>
Regards,
Andy
